用java去访问web service 提供的电视节目预告

思路：
1 用程序去访问 web service 服务.返回 xml文件。
2 用dom 去解析xml
3 用解析后的数据 生成 html文件

访问web service 的代码

public class StaticHTMLFile{		public static boolean PrintPage(String page, String url_addr) { 			URL url; 			String rLine = null; 			PrintWriter fileOut = null; 			InputStream ins = null; 			File file=new File(page.trim());			try { 				url = new URL(url_addr); 				ins = url.openStream(); 				BufferedReader bReader = new BufferedReader(new InputStreamReader(ins, 				"utf-8"));//获取编码为utf-8的文件 				file.createNewFile();				FileOutputStream out = new FileOutputStream(file); 				OutputStreamWriter writer = new OutputStreamWriter(out, "utf-8"); 				fileOut = new PrintWriter(writer); 				//循环取取数据,并写入目标文件中 				while ( (rLine = bReader.readLine()) != null) { 				String tmp_rLine = rLine; 				int str_len = tmp_rLine.length(); 				if (str_len > 0) { 				fileOut.println(tmp_rLine); 				fileOut.flush(); 				 } 				tmp_rLine = null; 				} 				url = null; 				return true;			} catch (IOException e) { 				System.out.println("error: " + e.getMessage()); 				e.printStackTrace(); 				return false; 			} catch (Exception es) { 				System.out.println(es.getMessage()); 				return false; 			} 			finally {//关闭资源 				fileOut.close(); 			try { 				ins.close(); 			} catch (IOException ex){ 			//关闭输入流出错 				ex.printStackTrace();				} 			}		}	}

把xml解析成int[]

public class DomXml2Int {	String fileName=null;//xml的文件	String tagName=null;//要提取的xml中标签的名字	public String getFileName() {		return fileName;	}	public void setFileName(String fileName) {		this.fileName = fileName;	}	public String getTagName() {		return tagName;	}	public void setTagName(String tagName) {		this.tagName = tagName;	}	public List<Integer> builder() throws ParserConfigurationException, SAXException, IOException{		List<Integer> ids=null;					  ids=new ArrayList<Integer>();		DocumentBuilderFactory dbf=null;		DocumentBuilder			db=null;		Document                d=null;		NodeList 				nl=null;		Node					n=null;								dbf=DocumentBuilderFactory.newInstance();								db=dbf.newDocumentBuilder();								d=db.parse(fileName);								nl=d.getElementsByTagName(tagName);		//循环取出每个Node的值		for(int i=0;i<nl.getLength();i++){			n=nl.item(i);//得到每个node			//System.out.println(n.getTextContent());			ids.add(Integer.valueOf(n.getTextContent()));		}		  return ids;	}}

提取电视节目的代码

public class DomXml2String {	/**	 * @param args	 * @throws ParserConfigurationException 	 * @throws IOException 	 * @throws SAXException 	 */	public static void main(String[] args) throws ParserConfigurationException, SAXException, IOException {	    System.out.println(new DomXml2String().builder("tt.xml")[0]); 	    System.out.println(new DomXml2String().builder("tt.xml")[1]); 	}	//解析xml到数组中去	 public String[] builder( String xmlFilePath ) throws ParserConfigurationException, SAXException, IOException{		 String[] tvShow= new String[2];		 StringBuffer tvShowTempAM=new StringBuffer();		 StringBuffer tvShowTempPM=new StringBuffer();		 DocumentBuilderFactory dbf=null;		   dbf=DocumentBuilderFactory.newInstance();           DocumentBuilder db=null;	           db=dbf.newDocumentBuilder();           Document d=null;                  d=db.parse(new File(xmlFilePath));           NodeList n=null;                    n=d.getElementsByTagName("tvProgramTable");           Node node=null;           //循环得到每个节点的值           for(int i=0;i<n.getLength();i++){        	    node=n.item(i);        	   //System.out.println(i+node.getChildNodes().item(3).getTextContent() );        	   if(node.getChildNodes().item(3).getTextContent().equals("AM")){        	    //System.out.println(i+" is am" );        	    	tvShowTempAM.append(node.getChildNodes().item(1).getTextContent()+""+node.getChildNodes().item(5).getTextContent()+"<br>");        	    }else{        	   //	System.out.println(i+" is pm" );        	    	tvShowTempPM.append(node.getChildNodes().item(1).getTextContent()+""+node.getChildNodes().item(5).getTextContent()+"<br>");        	    }           }		 tvShow[0]="AM\n"+tvShowTempAM.toString();		 tvShow[1]="PM\n"+tvShowTempPM.toString();			 return tvShow;	 }}

提取湖北省的所以电视节目

public class TVRequestWebServiceTest {	/**	 * @param args	 * @throws IOException 	 * @throws SAXException 	 * @throws ParserConfigurationException 	 * @throws TemplateException 	 */	public static void main(String[] args) throws ParserConfigurationException, SAXException, IOException, TemplateException {        List<Integer> dstIds=null;        List<Integer> pdIds=null;        String[] tvShow= new String[2];        //根据省的id得到省的所有电视台的id(数据保存到dstIds.xml)		StaticHTMLFile.PrintPage("E:/workspace/spring2Test/dstIds.xml",				"http://www.webxml.com.cn/webservices/ChinaTVprogramWebService.asmx/getTVstationDataSet?theAreaID=17 "                   );		//根据dstIds.xml得到电视台的id(int)		DomXml2Int dxi=null;				   dxi=new DomXml2Int();				   dxi.setFileName("dstIds.xml");				   dxi.setTagName("tvStationID");				   dstIds=dxi.builder();		DomXml2String dx=null;			   dx=new DomXml2String();	    String2Html s2h=null;		//循环每个电视台得到每个电视的所以频道id		for(int i=0;i<dstIds.size();i++){			StaticHTMLFile.PrintPage("E:/workspace/spring2Test/pdIds" +					"_" +					dstIds.get(i) +					".xml",					"http://www.webxml.com.cn/webservices/ChinaTVprogramWebService.asmx/getTVchannelDataSet?theTVstationID=" +					dstIds.get(i)	                  );			dxi.setFileName("pdIds_"+dstIds.get(i)+".xml");			dxi.setTagName("tvChannelID");			pdIds=dxi.builder();//获得每个电视台的所以频道id			//测试			/*for(int j=0;j<pdIds.size();j++){				System.out.println(dstIds.get(i)+":"+pdIds.get(j));			}			//测试成功			*/			//循环每个频道得到频道的电视节目			for(int j=0;j<pdIds.size();j++){				StaticHTMLFile.PrintPage("E:/workspace/spring2Test/pdIds" +						"_" +						dstIds.get(i)+						"_" +						pdIds.get(j)						+						".xml",						"http://www.webxml.com.cn/webservices/ChinaTVprogramWebService.asmx/getTVprogramDateSet?theTVchannelID=" +						pdIds.get(j)+						"&theDate=" +						"2009-02-20" +						"&userID=" 		                  );			tvShow=	dx.builder("pdIds_"+dstIds.get(i)+"_"+pdIds.get(j)+".xml");			//测试 tvShow			/*System.out.println(tvShow[0]);			System.out.println(tvShow[1]);			*测试成功AM07:00晨曲07:03重播:美嘉购物14:00重播:都市商报14:30重播:美嘉购物PM18:15元富财经18:37都市商报19:09股海罗盘19:30湖北新闻联播19:51天气预报19:55直播:美嘉购物23:55重播:美嘉购物02:00夜曲			*			*			*/			//把tvshow的数据输出到html()			s2h.builderHtml(tvShow, dstIds.get(i), pdIds.get(j));			}		}	   	}}

把数据转换成html的代码

public class String2Html {	public static void builderHtml(String[] strS,int i,int j) throws IOException, TemplateException{		//初始化freeMarker		File file=null;			 file=new File("E:\\workspace\\spring2Test\\htmlTest\\");	   Configuration cf=null;	   				cf=new Configuration();	   				cf.setDirectoryForTemplateLoading(file);	   	Template template=null;		   			 template=cf.getTemplate("tvShow.ftl");	   	Map<String,String[]> root=null;	   						 root=new HashMap<String,String[]>();	   				root.put("tvShow", strS);	   	Writer out=null;	   		//下面的文件名: 电视台id_频道id_时间.html  	   	out=new BufferedWriter(new OutputStreamWriter(new FileOutputStream(new File("E:/workspace/spring2Test/htmlTest/"+i+"_"+j+"_"+".html")),"utf-8"));	   	template.process(root, out);	}}

//这里是原始的代码，需要好好整理整理。最好用soap
